I was reading Storey's guide and on page 115 they talk about adding oats to pullet grower to ensure layer pullets grow slowly. My girls are 7.5 weeks old now and I am just transitioning from chick starter to pullet grower this week. Has anybody followed this recommendation and then added oats? What type of oats are added? Is it regular, old-fashioned oatmeal? Is it special oats purchased at the feed store?
